You can try to remove the power from the FTDI. Sometimes the chip inexplicably 
hangs ... 
If you read the flash back (-U r:flash:out.hex:i), does the memory match the 
hex file you programmed or does that read hang too?
If I remember correctly, avrftdi had a faulty polling routine which could 
result in an infinite loop.
I do not remember, however, in which version I fixed that and if I even 
committed a patch - so try the SVN-version.

If the hang occurs on the last page, you don't have a problem, since the flash 
will be programmed correctly. However avrdude will not be able to verify the 
memory or terminate properly.

Hope this helps,
Hannes
